I've worn sleep trackers before -- both FitBit and Misfit -- and neither has been as comprehensive as this Sleepon monitor. It not only measures the amount of time asleep and the restlessness/deep sleep, but also measures heart rate, oxygen levels, and through those, sleep apnea. It also gives you a summary of your sleep patterns compared to the larger population, whether you sleep more or less, where your deep sleep duration falls, and how your toss-and-turn index compares. This is all displayed through a smartphone app that you download for free. (I use the iOS version.)

This was easy enough to use and got results consistent with what I get from my Apple Watch. I tried checking my teenager's sleep, and he refused to wear it, though (he won't wear any kind of jewelry - no bracelets no rings nothing). I'm going to keep trying, because apnea runs in his dad's family. Anyway, I had a bit of a learning curve, but it was short and mostly easy to figure out. Initial charging instructions are important. Once you get through all that, it's easy.

Comfortable to wear while sleeping. Lots of good info in the report.

This unit is very interesting. It seems to measure quite a bit about your sleep habits and via the phone app, graphs out your night. You wear the unit on your finger as you sleep. I was definitely aware of the unit, so I found it annoying to sleep with. I'm sure you'd get used to it in time, though. It's very lightweight,less than 10g as they said and unobtrusive. I'm not sure how accurate it is or how I would measure that so I guess I'll take its word for it. It provides a great deal more data than other sleep monitors I've used.

I expected this to bother me trying to sleep, but the silicone ring that holds the sensor is very comfortable. It gathers a wealth of information about your quality of sleep including heart rate, oxygen level, incidents of sleep apnea, tossing and turning frequency, time spent in deep, light and REM sleep. I am very impressed with the daily/nightly reports generated. I can get 3 nights to a charge. This is a surprisingly good product - much better than sleep monitoring smart watches it have used.

Got my ring yesterday, it seems a very well made, quality piece of equipment. Would you consider an extra small ring size too? I have to wear the smallest ring on my biggest finger and even then it’s slightly loose. It also says it’s best worn on index or ring fingers, and I must wear it on my middle finger.

I have tried many sleep trackers over the years and have had sleep studies. This is the best sleep tracker that I can use everyday and it accurate with detailed reporting. Shows RHR, HR, Sleep Details (Deep, Light, REM), Sleep Apnea Index, Toss/Turns, Blood Oxygen level, Sleep Debt (how much more sleep you need). Insightful and actionable.

I was always looking for this super-convenient device for my sleep apnea! It is really costly and uncomfortable to check this in the hospital. But now, I can check on my own from home! Super love this little device!

There was Something wrong about your sleeping stages. Usually REM the last and deep Sleeping stage but you make it as the Second stage. It seems not match with the normal one.
